Gman,
I concur with MeWorry? It is a very simple format but it sometimes just takes a little practice. Whether you have your friend ask you a few questions in that format, or get a professional service, I think you'll find a little practice might help. Emerald Coast provides a money back guarantee if you don't go on to phase II.
